Yeah, pardon me if I doubt the Russians would be so silly to send nuclear armed aircraft into someone else’s airspace. That’s a great way to lose the nuclear armed aircraft, their nuclear weapons, and the pilots.

If the story is true, and I don’t know about that, then the “airspace” would be the air above an island in the middle of the Baltic, so not exactly like sending your plane deep behind enemy lines.
